Compression code for transferring rate matched data between devices

摘要

A block of N-bit symbols is compressed to reduce transfer bandwidth between two devices. A plurality of locations within the block of N-bit symbols is identified in which a same known N-bit symbol is to be located. The known symbol in each of the plurality of locations is replaced with a substitute 1-bit symbol having a first value. Each remaining symbol in the block of N-bit symbols is marked with a marker bit having a second value. The compressed block of marked N-bit symbols and substitute symbols is transmitted from one device to another device and then decompressed by replacing the substitute symbols with known symbols and removing the markers to restore the original block.
